Java RandomAccessFile setLength但是用于二进制文件的启动

Question

I've been reading on RandomAccessFile and understand that its possible to truncate the end of a file by setLength to a length shorter than the file. Im trying to copy just the "end" of the file to a new file and truncate the beginning.

So for example: I want to delete the first 1300 bytes of a file and copy the rest of the file into a new file.

Is there any way of doing this?

Cheers

您是否考虑过使用RandomAccessFile搜索方法寻找1300个字节，然后从偏移量开始读取文件的其余部分并使用另一个RandomAccessFile（或不同的流输出）来创建一个新文件，其中包含您从原始文件中读取的值文件以你指定的1300字节偏移量开始？
